Butterfly bushes and winter of 2014
Has anyone lost any butterfly bushes? The severe winter really took a toll on mine. For years I had one that was quite large and actually came up each spring from the dormant stems about 3-4 feet off the ground. This year when I saw there was no growth appearing even after a hard pruning, I pretty much cut it down to the base. I was encouraged when I saw new shoots coming up, but very atypically for this usually vigorous grower - the shoots are spindly and not looking too energetic. Do you think I should continue to hang in there with it or just replace it? I'm wondering if there was too much root damage since the base of the plant was buried under ice and snow for literally months during the winter we just had. Recently I am trying some super phosphate fertilizer to see if I can encourage some better growth. My other bushes are coming up pretty nicely from the base.
Also, if I do replace what was my largest one that isn't doing well, I want to put in one that grows the largest. Is there any particular species that grows the tallest? I'm thinking probably davidii but thought I'd check. I will sure miss seeing those masses of butterflies this summer that gathered around this bush that used to grow to probably 6-7 feet and quite wide also.
